How do you find the gravitational potential of two masses for any position around them that is outside the masses?  Specifically, take the Earth and the Moon as an example.  We need big masses like these because G is so small.  Gravity is very weak.  When we do electricity, we can work with smaller amounts of matter and smaller distances because electrical forces are stronger than gravitational forces.  Here are the

Hi, can anyone solve this with a detailed explanation.   The electron in a hydrogen atom is initially at a distance 2.12 Å from the proton, and then moves to a distance 0.529 Å from the proton. (a) Calculate the change in the force between the proton and the electron. (b) Calculate the change in the potential energy between the proton and the electron. (c) Calculate the change in the velocity of the electron.
